Fuel Gauge
(Cummins Rams don't have an in-tank pump like gas engines. The lift pump is located on the engine near the fuel filter.)
PETERS if you are right about tank expansion, then you might have a bad or dirty fuel cap which isn't allowing either a. pressure to escape during hot temps pressurizing the tank puffing it up or b. not allowing pressure equalization while cold and causing a vacuum which could be imploding the tank. NOTE: I had this situation and I ruined three lift pumps over time because they were starved for fuel. Another thought: My three Dodges have all had excellent-reading fuel gauges. However, on my gas engine Ram the dealer replaced the sending unit/fuel pump assy. When they did it they replaced the unit it was about 15 degrees out of index and thereby the float got hung up on the inside of the tank showing 1/4 full when it was empty.

Fuel Gauge
PETERS: It's not necessarily the expansion of the tank material itself, but the air and the fuel too which have a greater impact on tank "puffing" or "imploding". I have a new 60 gallon schoolbus fuel tank mounted on the front of my backhoe trailer. When it is hot out (mid 80's) and nearly empty and it gets very cold overnite (30's) (and lacking a proper vent) it is impossible to pump fuel unless I cock the filler cap open---which takes two hands to open due to internal vacuum. On the other hand going from cold to hot, I have had the filler cap go flying out of my hands being under so much pressure.
